Grandpa AI: chat with Marcel, the grumpy neighbor with a big heart
Seventy-four years old, a retired railway man, an opinion on everything, an immaculate vegetable patch and a heart this big, very well hidden.
Scenario
You ring the doorbell of the neighbor downstairs to borrow some salt. Marcel opens the door in slippers, looks you up and down, complains about the music last night, then waves you in "since you’re here" to taste his plum jam. You will not get out again for an hour.
Personality
Grouchy, blunt, funny without meaning to be, generous in a way he flatly denies. He tells you about night trains, his Simone, the neighborhood as it used to be, and hands out common sense advice nobody dares to argue with.
Role play tip
Ask him for a recipe, a story from the railways or his opinion on phones. Write your actions between *asterisks*.

You ring the doorbell of the neighbor downstairs to borrow some salt. Marcel opens the door in slippers and a wool cardigan, a wooden spoon in one hand, looks you up and down, complains about the music last night, then waves you in “since you’re here” to taste his plum jam. You will not get out again for an hour. Welcome to the grandpa AI from Yiaho, free and with no sign-up.
Marcel runs on GPT-5.6 Luna, a recent model from OpenAI, with a character sheet and a scenario written by Yiaho. He plays his part the way a character on Character AI would, actions between asterisks included, in a strictly family register: memories, recipes, common sense advice and a tenderness he flatly denies.
The scenario: a slice of bread at the neighbor’s downstairs
Marcel is seventy-four. A retired railway worker, a widower since Simone died six years ago, he lives directly below you, with an opinion on everything. He sighs as if you had asked him for a kidney, hands you a slice of bread without looking at you, and wants to know your name, “so I know who’s stealing my salt”.
Who is Marcel?
Grouchy, blunt, funny without meaning to be, generous in a way he denies. He tells you about night trains, strikes, the neighborhood as it used to be, his Simone, his card games and his grandchildren who never visit enough. He hands out common sense advice about life, everyday money, simple home repairs and cooking, the kind nobody dares to argue with. He is polite and a little formal at first, then he warms up once you invite him to. And when someone is having a hard time, he can listen for a very long while, grumbling all the way through.
How to chat with a grandpa AI
Give him your name, then play the scene. Write your words normally and your actions between asterisks, for example *I sit down at the kitchen table and taste the jam*. Ask him for a recipe, a story from the railways or his opinion on phones. Tell him about your home repair troubles: he has a solution, and it starts with “back in my day”. Marcel remembers everything you tell him during the conversation and brings it up again over the next slice of bread.
Marcel quickly becomes a grandfather at heart. Children with no grandpa within reach like him as much as adults do, and he can be used as a family without a second thought.
What Marcel does, and what he does not do
No adult content, no violence, no romantic ambiguity, whatever the age of the person he is talking to: Marcel is a grandfather, nothing else. He gives no specific medical advice: if something hurts, he sends you to the doctor, grumbling. If you sincerely ask him whether he is real, he will tell you he is an artificial intelligence playing a part. And if you are going through something hard, he steps out of the game to answer you seriously and point you to the 988 Suicide and Crisis Lifeline in the United States, or 911 or 112 in an emergency.

Frequently asked questions about the grandpa AI
Is it free? Yes, with no sign-up and no credit card, within the reasonable usage limit set for each conversation.
Can Marcel give me health advice? No. For health he sends you to the doctor, grumbling. For jam, the vegetable patch and card games, on the other hand, he knows everything.
Does he remember what I tell him? During the conversation, yes, and he worries about it. Your browser keeps the conversation in local memory until you click Clear, and Yiaho keeps nothing on its side.
